About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX220-100
The AirTAC SAIJ63X220-100 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a generous 100 mm adjustment range, allowing you to dial the effective travel down anywhere within a 120 to 220 mm window. Delivering 1559 N of pull force at 0.5 MPa, it handles robust actuation while utilizing a PT tapered port thread and an SUS420J2 stainless steel rod for enhanced corrosion resistance.
Because the rear screw acts purely as a mechanical stop to set the end position, it does not lock the load without live air pressure. For load-holding without continuous air, an external pilot-operated check valve or a related AirTAC SAIL locking cylinder is required. This model uses the standard SAIJ mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX220-100 Is Used
Product Changeovers
Quickly reconfigure the end-stop position for different packaging lengths on a single line using the 100 mm adjustment window.
Machine Setup
Fine-tune the exact retraction point during commissioning without machining new hard stops or changing the cylinder.
Variable End Stops
Dial in the precise 120 to 220 mm travel distance required for multi-format assembly tooling.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX220-100 the Right Cylinder?
Choose this 63 mm bore when you need higher thrust than a 50 mm cylinder (which provides 825 N pull at 0.5 MPa) but want to avoid the larger footprint of an 80 mm unit. The 100 mm adjustment range is ideal for machines running multiple product sizes, allowing you to reconfigure the end-of-stroke position during changeovers without swapping the cylinder or adding external stops. If your process requires a fixed end position every cycle, a standard SAI cylinder is simpler.
When replacing an ISO 15552 cylinder, match the 63 mm bore, 220 mm nominal stroke, 100 mm adjustment, PT port thread, and mounting style. Note that this configuration lacks a magnet (-S not specified), so it will not trigger CMSE or DMSE sensors. With a 220 mm stroke, the 20 mm rod diameter handles moderate side loads, but long unsupported travel still demands an external guide.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX220-100 FAQ
At 0.5 MPa operating pressure, this 63 mm bore cylinder provides 1559 N of pull force and 2182 N of push force. At 0.7 MPa, the push force increases to 2182 N.
The rear adjuster screw allows you to shorten the effective stroke by up to 100 mm. This creates a usable travel window of 120 to 220 mm, letting you set the exact end position without replacing the cylinder.
